Transcript of Weathering

Ice wedging is a mechanical weathering process caused when water freezes inside the cracks of rocksWater may seep into a rock. As the water turns to ice, it expands and pushes against the sides of the crack, therefore, breaking the rock.Mechanical weathering occurs when rocks are broken apart by physical processes. One way of mechanical weathering is Ice Wedging.

ClimateMechanical weathering is most dominate in cold climates with medium amounts of rainfall, where chemical weathering is dominate in hot and wet climates.A reason mechanical weathering is dominate in cold climate, is Ice wedging.Chemical weatheringChemical weathering occurs when chemical reactions dissolve minerals or change them into different materials.Sometimes chemical weathering can change a mineral to a different substance!For instance, iron, if it is chemically weathered, it turns into rust.Mechanical weatheringNatural EffectsIce WedgingWhat is weathering?Weathering is surface processes that weaken and break rock into smaller and smaller pieces. The two types are chemical and mechanical weathering.Types of WeatheringBy Jesse Hanks and Max Fullerton#FERICESay water and nutrients get into a rock. Then a seed comes along and decides to settle into that rock. the seed starts to grow and make roots. As it grows, the roots crack the rock.Small burrowing animals dig sediment in the soil. The animal pushes these sediments to the surface. Once the sediments are out of the ground, a weathering process begins.We apologize for the picture that was previously here. We do not mean any harm to people that suffer this condition. It was completely inappropriate and unrelated to the subject. We are very sorry.
